Solid sphere but not indivisible
John Dalton
Elements of a chemical compound are bonded together by electrical forces
Humphry davy
Relationaship between the amount of electricity used & the chemical reaction that occur
Michael faraday
Electron —> electron ions

Rutherford
Nucleus
Rutherfors
Atoms consist of a positive nuclei surrounded by clouds of electrons at large distance
Rutherford
No. of PROTONS determines its identity
Moseley
the no of protons is the Atomic no.
Moseley
Neutrons
Chadwick
Electron revolving around its nucleus in a circular orbit
Niels Bohr
Planetary model
Niels Bohr
Wgen electrons is excited, ir absorbs energy
Niel bohrs
Electrons occupy only certain energy level
Niels bohr
Wave-like nature of electrons
Brogli
Modern atomic model
Schrondinger
Wave equation
Schrondinger
Wave properties of matter
Schrondinger
Uncertainty principle
Heisenberg
It is not possible to determine the exact momentum & exact position of electrons at the same time
Heisenberg’s uncertaity principle
